PROPELLING AND STEERING MECHANISM FOR AlR-SHlPS- Specification ofLetters Patent.

Patented June 25, 1907.

Application filed July 19, 1906. Serial No. 326.858.

- its object to provide improved apparatus of this class; and with thisand other objects in view the invention consists in the construc tion,combination and arrangement of parts to be hereinafter more speclficallypointed out, described and claimed.

The invention is fully disclosed in the following specifications, ofwhich the accompanying drawingsform a part, and. in which the separateparts of my improvement are designated by suitable reference charactersin each of the views, and in 'which Figure 1 is a side elevation of anair-ship with my propeller attachment. Fig. 2 is a plan view of the samewith the rudder attached. Fig. 3 is a side elevation showing thepropeller turned at an angle with the body of the air-ship. Fig. -l is aplan view of the invention showing the propeller elevated at an anglewith the body of the air-ship.

Like numerals of reference indicate like pal ts in the several views.

The numeral 2 indicates an air-ship frame of ordinary construction towhich the propelling mechanism is attached.

Referring now to the propelling mechanism, the numeral 3 indicates amotor carried by the cross rods 4 which connect the lower horizontalrods of the frame.

5 indicates a sprocket-wheel carried by the motor and connected by achain with sprocket-wheel 6, said sprocket-wheel being arranged on theconnecting shaft 7 which is journaled in the end 8 of the air-shiframework. The end of the connecting s aft carrying the sprocket-wheelis journaled in the supporting-frame 9 which frame comprises a crosspiece extending from side to side of the 1 lower framework of theair-ship and a vcrti- 5 I cal portion perpendicular to the cross pieceand extending from the same to the'upper horizontal portion of theair-ship frame.

The end of the connecting shaft journaled in the air-ship frame isbifurcated as at 10 truding from said hub.

and a pivot connects the two branches of the same. A block 12 isarranged to turn upon said pivot. Another pivot extends through block 12at right angles to the first pivot and connects the prongs of thebifurcated auxiliary shaft 13. Block 12 with the two pivots forms a conling for the connecting shaft 7 and the auxiliary shaft 13. The end ofthe air-ship carrying the propeller blades is prov vided with asupplementary framework 14 welded thereto for the purpose of supportingpart of the propelling mechanism. Said supplementary framework is ofsuitable shape and pro'vided at its free. extremities with eyes 15, forholding in' position the hub 16, upon which part of tlie propellingmechanism swings. The eyes 15 engage pins 17 pro- The hub 16 is furtherprovided with pins 18 which engage the eyes 19 of the swinging frame 26,in the hearing of which is journaled the auxiliary shaft- 13 carrying onits free extremity the pro,-

peller hub 21 to which the propeller blades 22 are attached.

- Referring now to supporting frame 9. the same is provided with anupright 23 to which is pivoted a lover Z-I, the said lever 24 having anarm 25 pivoted thereto, the other extremity of said arm being pivoted toan upright 26 welded to the hub 16 thus forming a means for swingingsaid hub on its pins resting in the supplenientaryframework 14. It isreadily seen that since the swinging frame is attached to hub 16 and theauxiliary shaft 13 carrying the propeller blades is journaled in saidframe, the inclination of-thc hub 16 will raise or lower the propellerblades with ref erence to the body of the air-ship. Another upright27'is arranged on the supporting frame 9 and pivoted to its upperextremity is another lever 28 having an arm '29 pivoted thereto, theopposite ektremity of said arm being pivoted to an auxiliary/ arm 30having its opposite extremity welded to the rudder 31 which is arrangedon the rear end of the ai1,'shi which is understood to be the end mostistant from the propeller blades. A lever-rack 32 extends fromfthe upperhorizontal rod of the air-ship frame and is provided with notches 33 forthe retention of the lovers when placed in the same. In this manner thepropeller blades or the rudder may be elevated or depressed withrelation to the air-ship and held at any desired angle 'motor and therudder I provide a steering frame.

and imparts l catedou Sitld shaft and by means of the coupling bewheel34 supported on a suitable sub-frame and provided with a lever 35 forturning said wheel. The periphery of said wheel is grooved to carry aguide rope 36 which rope extends from said wheel toward the front of theair-ship, through the eyes 37 of the'crossrod 38, (which rod is forthepurpose of keeping the guide rope out of the way of the body of theair-ship) and is connected with hooks 39 which engage the ears 40 of theswinging By means of the steering wheel it will be seen that thepropeller blades and support therefor can be turned from left to rightor vice versa and so guide the ship in its course.

Qperation: When the motor is turned'on the sprocket-wheel carriedthereby revolves ion to the sprocket-wheel lone connecting shaft whichturns tween the connecting shaft and the auxiliary shaftthe latter isalso caused to revolve in its bearings and as the propeller hub' isfixed to the free end. of the auxiliary shaft it revolves together hthe'propeller blades and in this manner 1211.9 air-ship is propelled.The motion of the air-ship can be reversed by reversing the motor. Therudder is intended to facilitate the upward or downward flight of theship by inclining it in the direction in which travel is desired. It isunderstood the air-ship is to be provided with a balloon of suitabledimensions for the purpose of floating the ship.

I Having thus described my invention, what I desireto claim as new andsecure by Letters Patent is.

1. In a ropelling mechanism, a motor, a s rockets iaft suitablysupported and carrying a sprocket wheel engaging the aforesaidsprocket-wheel, an auxiliary shaft coupled to said connecting shaft,propeller blades arranged on said auxiliary shaft, a hub 16 carried bysupplementary framework of the airship, a swinging frame pinion'ed tosaid. hub and carrying said auxiliary shaft in its bearings. y

2. In anai'r-shipfa propeller comprising a motor, a sprocket-wheelcarried thereby, a

connecting shaft arranged directly above said motor and carrying asprocket-wheel to engage the aforesaid sprocket-wheel, an auxiliaryshaft coupled to said connectingshaft, propeller blades carried by saidauxiliary shaft, a swinging hub carriedfby supplementary framework ofthe air-ship, a swingin frame pinioned to said hub and having'sai eelcarried thereby, a connecting.

, hub carried by supplementary framewor of theair-ship, a laterallyswinging frame pinioned to said hub, an upri ht welded to said.

hub, anarm pivoted to said '..ipright, a lever connected to said arm anda lever-rack carried by the upper framework of the machine for retainingsaid lever when at rest.

4. In an a r-ship, a steering ap aratus comprising a steering Wheel andsuita is sup-- portm frame therefor and a controlling leverv carrie bysaid wheel, a cross. rodcarr ed by the framework of'the machine andhaving eyes in its extremities, a l aterally'swinging frame supported atthe front endof theairship and designed to steerit horizontally, earscarried by said swinging frame, a guide rope extending from the steeringWheel, assing through the eyes of the cross rod an nating in said ears.

5. In an air-ship, a steering apparatus comprisin a steering wheel, alaterally swinging frame pivoted on-the front of the air-ship, a guiderope connecting said steering wheel and swing'in frame, a rudderarranged on the rear of t e ship and means for raising or lowering thesame to facilitate .the upward ordownward motion of the air-ship.

6. In an air-ship, a steering apparatus comprising a steering wheel andlever therefor, a laterally swinging frame pivotedto the front frameworkof the. air-ship, means conterminecting said frame and steering wheel,.a rudder arranged on the reanof the air-ship, an auxiliary arm weldedthereto for raising or lowering saidrudder, a connecting arm iv.- otedtosaid auxiliary arm',a; lever carrie by the framework ofthe air shipand pivoted to said connecting arm and a lever-rack extending from theupper framework ofthe air-ship and designed to engage the said leverwhen the same is at rest.

In testimony thatI' claim the foregoing as my=own, I have hereto affixedmy signature the presence of two witnesses.
